The DCMT-4000 is a Reliable Driveway Alarm Sensor that Detects When Cars Enter Your Property

Dakota Alert’s DCMT-4000 is a driveway alarm sensor with a range of up to 1 mile.   This means when the DCMT-4000 is triggered, it will transmit a signal up to one mile away (5,000 ft.) to one of the two compatible 4,000 alert receivers, the DCR-4000 and the RE-4K Plus.

This state-of-the-art sensor is passive infrared, triggered when the combination of heat and movement is detected in the monitored zone.   Users typically place the sensor on one side of the driveway so the invisible PIR beam shoots across the driveway so it can detect cars as they enter.  The sensor is outdoor rated.

How the Sensor Works

The DCMT-4000 is a passive infrared sensor/transmitter compatible with the DCR-4000 & the RE-4K Plus Dakota Alert receiver. The sensor shoots out a narrow beam across a driveway. When a car or person passes through the monitored zone, it immediately sends a wireless signal up to 5,000 ft. away to a compatible receiver.

Jumper pins inside the transmitter/sensor allow you to change different settings on the sensor according to your needs.

  1.  Sensitivity (or range) of the sensor according to your needs.    For example, the low setting will create a detection zone up to 25 ft. across.  A high-range setting will create a detection zone of 100 ft. across.
  2. Turn the LED on or off.  When the sensor is transmitting, you can determine whether you want an LED to show.
  3. Filter on or off.  If you are using the sensor outside, it is recommended to turn the filter “on” to filter out triggers from small objects like falling leaves.  Setting the filter to “off” makes it very sensitive and is recommended for indoor use.
  4. Reset changes the time between activation or triggers.  It may be set to reset 10 seconds after the trigger or 120 seconds after the trigger.  If you have a busy driveway or another area you monitor, you may want to use the 120-second trigger so it does not go off as much.

Driveway Monitor Sensor Product Features:

  • Low range-25 ft., Medium range – 50 ft., High range – 100ft.

  • One-year manufacturer’s warranty

The sensor is not standalone and must be used with a compatible Dakota Alert receiver.  For more information on these receivers, please click the links above for the DCR-4000 and the RE-4K PLUS.  Both receivers are indoor rates and may be placed up to 5,000 ft. from this transmitter.  Multiple transmitters/sensors may be paired with receivers (up to 16 per receiver), and each transmitter may have one of 16 available tunes or melodies chosen on the receiver.

Drive way alarm

Really satisfied with. It works as it should but only one thing wrong it could use a longer cord from probe to the box about 100 foot cord. So you can hide the box.

Thank you for your feedback! We are glad to know that you are happy with the product and that you think that it could use a longer cord. We will definitely consider adding a longer cord to future versions of the product.

Great product !

Bought this Dakota alarm to replace a 20+ year old Dakota alarm. Really like the choice of sounds and the long range of the detector. Do wish it had a simple on/off switch on the receiver. Definitely recommend Dakota alarms.

Thanks for the review! We're glad you're enjoying the DCMA-4000 Dakota Alert Premier Driveway Monitor. We do have a switch on the receiver so you can easily turn it on and off.
